Everybody else is mentioning this Donnie Darko-ish video, so I figure I should, too.
Bat for Lashes is the stage name of British songwriter, musician and multi-media artist Natasha Khan. She studied film and music at university, both of which strongly influence her work. I copied that last sentence from a blog somewhere because it's so inane. Enjoy.
I forgot to mention earlier that Doc Logan posted this video too.
